Charger Fault (Service) Conditions
LED Label
LED Color
Fault
Reverse Polarity
Red
Indicates a reverse polarity situation
Check DC Connections, ensure po (RED) and negative - (BLACK and/or YELLOW)
connections are attached accordingly
DC Volts Low
Amber
DC system voltage is less than 11.0 VDC
Bring system voltage over 11.0 VDC, check battery(s) condition and replace as necessary.
DC Volts High
Red
Indicates a high DC voltage from an outside source
such as a failed alternator
Using a multi-meter check alternator(s) output, generally over 15VDC. Determine if fault exists
in regulator or alternator, solar panel, wind generator etc. Replace as needed.
Charger High Temp Amber
Charger has shut down due to high temperature
Generally this indicates that the unit has been installed in an area with a very high ambient temperature. This
unit is designed for use in an engine room, if installed in an engine compartment; ensure that there is proper
ventilation in the space for the charger and other temperature sensitive components. If the installation area
temperature is 45° C (113° F) or more, move charger or add ventilation to lower ambient temperature. The
recommended maximum ambient temperature for installation is 45° C. (113° F)
Check Fan
Red
Fan failure
Ensure that the cooling fan can move freely and that no debris is blocking the fan movement.
Persistent fan problems require service from ProMariner.

Auto Temp Control Red flashing
High temp causes unit shutdown
See charger high temp above
Note: Installation is permitted in an environment of 45° C (113° F) and may result in output
of unit decreasing to protect the internal components and the performance of the unit.
